Hello yet again,
Setup:
HP Procurve switch:
- ports are assigned to "VLANs", but are untagged
Cisco 2948g L3 switch:
- not configured at all
- more of a router then a switch
Cisco 3500XL switch:
- not configured
Details:
- When I plug a cable into the HP switch in a port configured in the LAB vlan (172.16) I am assigned an address.
- If I run a line from the HP (plugged into lab) to a Cisco 3500XL switch and connect it then anyone I plug into that switch can now be assigned a 172.16 address.
- When I run a line to my Cisco 2948g L3 switch and plug it in the link comes up. If I plug in a user they are NOT assigned an address.
Goal:
I would like to have it so that I can use the Cisco 2948g L3 switch so that anyone who plugs in can be assigned an address.
Questions:
1. If the frames are untagged (on the HP) then are there really VLANs or are the ports just seperated by network subnets?
2. Why is it that the 3500XL switch has no trouble when I plug users into it (after the line has been ran from the HP).
3. Since the 2948g L3 acts more like a router, could I assign an address to the port connecting the 2 switches and use a routing protocol to share host information?
4. If I tag the frames on the HP switch, then could I just create a trunk line between the two switches? If so, I have found information on configuring a Cisco 2948g L3 to do 802.1q, but would I need to change anything on the HP (set the ports to use encapsulation 802.1q? I would think if I tagged them that it would automattically use 802.1q)
Does anyone have any thoughts. I was hoping this 2948 switch would go without issues, but sadly it is more complex then what I thought. Knowing the end goal does anyone have any ideas?
